This application is a continuation of U.S. patent application Ser. No. 16/697,427 filed Nov. 27, 2019, which is a continuation of U.S. patent application Ser. No. 15/614,720 filed Jun. 6, 2017, now issued as U.S. Pat. No. 10,495,172. Each of the aforementioned applications/patents is incorporated herein by reference.

TECHNICAL FIELD

The present disclosure relates to a structural element that provides load bearing support. In particular, the present disclosure provides an encapsulated material that can serve as a load bearing support for various types and sizes of industrial equipment.

BACKGROUND

There are several types of equipment used on or near well sites, compressor stations, refineries, and chemical plants such as compressors, treater units, cooling units, heaters, pumps, and the like.

Oftentimes, supports or foundations for such equipment involve the use of gravel or dirt pads built specifically for each type of equipment. Inclement weather can wash out these gravel and dirt pads, causing the equipment to become unstable. Moreover, building pads specifically for each type of equipment consumes time for pre-planning and constructing a pad suitable for each type of equipment. It can take several days to plan and construct these pads.

A need exists for an improved equipment base that can withstand inclement weather conditions. There is also a need for an equipment base that provides for a more time-effective and cost-effective means of the shipping, transporting, and installation into customer sites.

DETAILED DESCRIPTION

In an exemplary embodiment, as illustrated in FIG. 1, a system is generally referred to by the reference numeral 100 and includes an equipment base 102 that extends over the ground surface. An equipment unit 104 having a bottom or lowermost portion 105 is shown positioned on top of the equipment base 102 so that the equipment base 102 supports the equipment unit 104, preventing the lowermost portion 105 of the equipment unit 104 from contacting the ground surface. The equipment unit 104 can be or include any one or more devices, systems, apparatuses, including for example, an HVAC unit, a heat exchanger, a compressor, a pump, a mixing vessel, a reactor vessel, a storage tank, a surge drum, an engine, and the like and any combination thereof.

FIG. 2 is a top view of the equipment base 102 of FIG. 1. The equipment base 102 can be a single piece, or segment, or can include two or more segments. As shown in FIG. 2, the equipment base 102 contains a first segment 106, a second segment 108, and a third segment 110. The segments 106, 108, 110 can have any suitable dimensions. As shown in FIG. 2, the segments 106, 108, 110 can each have a length y and a width (x₁, x₂, or x₃). The length y and width x₁, x₂, or x₃ can vary to any suitable measurements depending on the equipment unit or units to be supported. In one or more exemplary embodiments, x₁, x₂, and x₃ can be independently from about 10 cm to about 5 m, such as from about 25 cm to about 3 m, such as from about 50 cm to about 2 m, such as about 1 m and y can be from about 10 cm to about 10 m, such as from about 25 cm to about 5 m, such as from about 50 cm to about 3 m, such as from about 1 m to about 2 m.

The segments 106, 108, 110 can be or include any suitable substrate. As used herein, the term “suitable substrate” is used synonymously with “substrate” and is meant to include without limitation, concrete, metal, polymeric solids, polymeric foams, such as expanded polystyrene (EPS) and expanded polyurethane, wood, paper fiber, fiberglass, fiber board, and gravel or any other substrate appropriate for the adhesion of an elastomeric coating, such as a polyurea elastomer coating. In one or more embodiments, a substrate includes one or more foam materials such as EPS, polyisocyanurate foams, polyurethane foam, polyvinyl chloride foam, polyimide foam, silicone foam, or microcellular foam or any suitable combinations thereof. The foam material can have any suitable density. For example, the foam material can have a density of about 0.5 pounds per square foot (lb/ft³) to about 8 lb/ft³ or more, such as from about 1 lb/ft³ to about 5 lb/ft³, such as from about 1.5 lb/ft³ to about 3 lb/ft³, such as from about 2 lb/ft³ to about 2.5 lb/ft³. In one or more exemplary embodiments, the foam material has a density from about 1.5 lb/ft³ to about 2.5 lb/ft³. The foam material can be substantially non-degradable or substantially degradable. In one or more exemplary embodiments, the foam material is biodegradable.

The substrate can have any suitable thickness sized to support any suitable equipment. In one or more exemplary embodiments, the substrate can have a thickness of from about 0.5 inch to about 12 inches or more, such as from about 1 inch to about 8 inches, such as from about 2 inches to about 6 inches, such as from about 3 inches to about 5 inches, for example about 4 inches. For example, a piece of equipment weighing approximately 50,000 pounds can be supported by EPS having a foam density of 2 pounds per cubic foot of foam weight, ranging from about 3 to about 12 inches in thickness.

The segments 106, 108, 110 can also include an elastomeric outer coating or layer. In one or more exemplary embodiments, the segments 106, 108, 110 are each encapsulated with the elastomeric layer. The elastomeric layer can be or include any polymeric material that can both create a fluid impermeable barrier layer and adhere directly to and/or at least partially penetrate the foam material of the segments 106, 108, 110. In one or more embodiments, the polymeric material can be or include polyurea. The elastomeric coating can have any suitable thickness. In one or more exemplary embodiments, the elastomeric coating of the liner 104 can have a thickness about 5 mil, about 10 mil, about 15 mil, 20 mil, about 30 mil, about 40 mil to about 50 mil or more.

The segments 106, 108, 110 can also have any suitable thickness sized to support any suitable equipment. In one or more exemplary embodiments, the segments 106, 108, 110 can have a thickness of from about 0.5 inch to about 12 inches, such as from about 1 inch to about 8 inches, such as from about 2 inches to about 6 inches, such as from about 3 inches to about 5 inches, for example 4 inches. For example, a piece of equipment weighing approximately 50,000 pounds can be supported by segments 106, 108, 110 having a thickness from about 3 inches to about 12 inches.

The segments 106, 108, 110 can form one or more seams 120 (two are shown) when positioned adjacent one another to form the equipment base 102. These seams can allow for moisture to pass between the segments and away from the equipment 104 and its lowermost portion 105, thereby preventing corrosion of the lowermost portion 105.

FIGS. 3 and 4 illustrate side views of the equipment bases and a couple of corresponding seams possible with the present disclosure. Straight seams depicted in FIG. 3 allow for any moisture from rainwater, for example, to pass through so as to prevent corrosion of the equipment from standing water effects. Interlocking seams seen in FIG. 4 also allow for moisture to seep away from the bottom of the equipment but also allow for another embodiment in which to piece or hold together the substrates. In one or more exemplary embodiments (not shown), the segments 106, 108, 110 can contain protrusions and corresponding recesses to form interlocking seams connecting adjacent segments together. In one or more exemplary embodiments (not shown), a strap with a cam buckle can be used to secure the segments 106, 108, 110 around the outer periphery of the edges and hold the pieces together until the pressure from the weight of the equipment is applied.

An exemplary method for constructing the equipment base 100 can include spraying an elastomeric coating onto the substrates to form the segments 106, 108, 110. The segments 106, 108, 110 can then be positioned adjacent to one another to form the equipment base 100.

An exemplary method for constructing the equipment base 200 can include spraying an elastomeric coating onto the substrates, or cores, of segments (such as segments 106, 108, 110, 202, 204, 206, 208), key members (such as key members 210) and side members (such as side members 212) so that the segments, the key members and/or the side members are each independently coated or encapsulated with the elastomeric coating. The coated segments (such as segments 106, 108, 110, 202, 204, 206, 208) can be connected to each other via key members 210 as shown in FIGS. 5 and 6. To complete the equipment base 200, side members 212 can be placed into any exposed recess in the outward facing side walls of the segments 202, 204, 206, 208 as shown in FIGS. 5 and 6.

The coated segments (such as segments 202, 204, 206, 208), the key members 210 and the side members 212 can form one or more seams when positioned adjacent one another to form the equipment base 200. These seams can allow for moisture to pass between the segments and away from any equipment 104 supported by the equipment base 200. In one or more exemplary embodiments, the seams can be at least partially filled with adhesives, caulking material, the elastomeric coating or any other type of suitable filler material.

Though particular shapes of equipment bases, its segments and other component parts are disclosed herein, the equipment base can include any suitable configuration, size, and shape. For example, the equipment base can have a triangular, square, rectangular, circular, oval, hexagonal, or octagonal footprint and can be from about 1 foot to about 50 feet or more in its largest dimension, such as from about 2 feet to about 20 feet, such as from about 3 feet to about 12 feet, such as from about 4 feet to about 8 feet, for example about 6 feet. In several exemplary embodiments, the equipment base has a square or rectangular footprint, and ranges from about 1 foot to about 20 feet in length, and from about 1 foot to about 20 feet in width.

The equipment bases disclosed herein can provide improved support for several types of equipment. The equipment can be or include any one or more devices, systems, apparatuses, including for example, an HVAC unit, a heat exchanger, a compressor, a pump, a mixing vessel, a reactor vessel, a storage tank, a surge drum, an engine, and the like and any combination thereof.

During operation, the equipment can produce vibrational forces that can affect the support of the equipment. An equipment base of the present disclosure can distribute vibrational forces produced by the equipment to enable vibration dampening. In one or more exemplary embodiments, an equipment base of the present disclosure can be configured to dampen movement of the equipment relative to at least one dimension. In one or more exemplary embodiments, an equipment base of the present disclosure can be configured to dampen the vibration of the equipment relative to the ground.

The equipment base can have any suitable properties that enable vibration dampening when supporting the equipment. Shear modulus (G) represents a material's response to shear stress and, for the equipment base, can be from about 2 MPa to about 10 MPa, such as from about 4 MPa to about 8 MPa, such as from about 4.5 MPa to about 6 MPa, such as from about 5 MPa to about 5.5 MPa, for example about 5.5 MPa. In one or more exemplary embodiments, the shear modulus of the equipment base can be about 5 MPa to about 5.3 MPa. A damping ratio (D) can be used to measure decay of oscillations in material after a disturbance and, for the equipment base, can be from about 0.1% to about 5%, such as from about 0.25% to about 2.5%, such as from about 0.5% to about 2%, such as from about 0.75% to about 1.8%, such as from about 0.9% to about 1.5%, such as from about 1% to about 1.3%. In one or more exemplary embodiments, the damping ratio of the equipment base can be about 1.2% to about 1.8%.

During operation, certain equipment, such as heat exchangers, pipe systems, turbines, compressors, and HVAC systems can undergo extreme temperature changes that can result in thermal expansion or contraction, which can affect the support of the equipment. The seams inherent in equipment bases of the present disclosure can act as expansion joints, allowing the circumference or footprint of the equipment base to expand and/or contract depending on the temperature change occurring in the equipment, thereby preventing damage to the equipment or the equipment base. In one or more exemplary embodiments, a footprint of the equipment base can expand and contract due to any expansion or contraction of the equipment.

Referring again to FIG. 5, in one or more exemplary embodiments, a piece of equipment (not shown) having four base legs can be positioned on top of the equipment base 200 so that the first base leg is on top of and affixed or otherwise connected to segment 202 via one or more screws, bolts, welds, or other fastening devices. In a manner similar to that of the first leg, the second leg can be affixed to segment 204, the third leg can be affixed to segment 208, and the fourth leg can be affixed to segment 206. During its operation, the equipment can expand via thermal expansion causing the first, second, third, and fourth legs move apart from each other, causing the footprint of the equipment base to expand.

In one or more exemplary embodiments, the equipment base can be located on any side of, on top of, and/or below the equipment when it is desired to insulate the equipment from heat exchange either from the bottom upwards or from the equipment downwards, or from side to side such as use with freezers or industrial piping. The equipment base can provide an effective, long lasting thermal insulation barrier. The equipment base can have an R-Value, measured in accordance with ASTM C518, of from about 2° F.ft²h/Btu to about 10° F.ft²h/Btu, such as from about 2.5° F.ft²h/Btu to about 8° F.ft²h/Btu, such as from about 3° F.ft²h/Btu to about 6° F.ft²h/Btu, such as from about 3.5° F.ft²h/Btu to about 5° F.ft²h/Btu, for example about 4.5° F.ft²h/Btu.
